If properly exposed and lit, I'd put money on the fact that the average visitor to your site (photographers included) wouldn't be able to tell the two side by side. What size are you going to have them posted on your site? 800 pixels on the long side maybe? Think about what the end result is, and the fact that no two monitors display colors the same way. Wouldn't you rather spend your hard earned money on more film and chemicals, and a flatbed scanner anyway?
